When Northstar Security agent Justine Shelby is assigned to protect world-famous author Rosalee Kane, the last thing she wants is help from the author's nephew, prickly but attractive FBI Special Agent Nelson Kane. Shelby is used to depending on herself and is content to work alone, but Rosalee and Kane make Shelby wish for something more. Of course, he may never forgive her if the assignment isn't successful, and the threats are escalating. Kane doesn't trust Northstar Security, blaming them for his close brush with death. His first encounter with the deceptively innocuous agent doesn't improve his attitude, but circumstances compel them to join forces. As things turn deadly and their every move is countered, Kane comes to depend on Shelby in a race against the clock to keep Rosalee alive. Shelby and Kane must uncover the deadly betrayal without dying first.
